Help with a Fan-Fiction story idea?

I am going to be writing a Fan-Fiction called the "Fan-Fiction Games" and it is going to be like the Hunger Games but with male and female tributes from each fandom. Each week I am going to update it, and based on information that I show for each tribute, readers will get to vote for who they think should/would die. Each chapter will show how a tribute dies, and will from the POV of a character that witnesses the death or kills the other character. I will have information about each tribute and a video showing there skill for those that don't know who they are. This story will be posted on fanfiction.net as well as wattpad. (my name is Anorafox on both of those sites if you want to check it out in the future)

Here are the fandoms:

1. Doctor Who (companions are fine, the doctor may not participate)

2. Lord of the Rings/Hobbit

3. Xena Warrior Princess/ Hercules the Legendary Journeys (demi-gods are fine, but no gods may participate)

4. Vampire Academy

5. Harry Potter

6. Percy Jackson (demi-gods are fine but no gods may participate)

7. Legend of the Seeker (the book series is called Sword of Truth)

8. Merlin

9. Once Upon a Time

10. Game of Thrones

11. Avengers

12. Pirates of the Carribean

I know all these fandoms, and so I am comfortable writing about them. You do not have to vote for tributes for each fandom, I just ask that you put the number next to it in case characters have similar names.

For example: 5. Sirius Black and Ginny Weasley

Thanks
